I thought I had posted this, but I don't see it now.

I used the stock tune (stock ECM in hand on the bench), to do a dpf delete tune. I uploaded that stock tune into a new ECM, shipped it to the customer with only dpf delete changes. He is getting all 8 of the 0268 fuel codes (injector rates).

Does that make any sense to anyone? The only change is dpf is disabled (deleted).
